FILLER COMPOSITION.

No Drawing.

To all whom it may concern:

Be it known that ALBERT F. FRENCH, deceased, a citizen of the United States of America, resident of Detroit, in the county of Wayne and State of Michigan, has invented certain new and useful Improvements in Filler Compositions, of which the following is a specification.

This invention relates to a filling compound, somewhat along the lines suggested in my Patent No. 1,352,741, granted Sept. 14:, 1920, disclosing a filler composition that may be placed in cracks, scratches and scarred surfaces and afterwards varnished or painted over to render the demarcations invisible. The present composition may be in liquid form and applied with a brush or it may be in the form of putty, especially for filling large cracks. 20 not materially contract and will permit of an injured surface being expeditiously repaired or finished, in contradistinction to treatments requiring hours and sometimes days to complete.

My composition consists of the following ingredients for compounding one gallon of the liquid filler Graphite (dry powder) 2 lbs.

Fullers earth 8 Gum thus 1 Turpentine.

To the gum thus is added enough turpentine to cut the gum and at the same time make one gallon of liquid filler which may be applied to a surface with a brush. Less turpentine is added to the ingredients when only a paste or putty form is required, and should the filler putty be too light or thin it may be thickened with white lead.

Should the liquid form of filler be too thick it may be thinned out by adding more turpentine.

In practice, a large crack is filled with the putty or paste form of the composition and after setting for about a half hour or less it is gone over with the liquid form of the composition. The liquid form dries rapidly and then paint or varnish may be applied.

thus as an adhesive and binding mate- In the composition the gum thus serves as a binder that will not contract; he fullers Application filed July 26, 1922. Serial No. 577,745.

In either form'it will earth as a body for the composition and the graphite to provide a smooth finish or polish to a surface.

This composition, particularly in its liquid form, mayybe'advantageously used in 5 the automobile industry for finishing automobile bodies. At present an automobile body, in its natural condition is provided with what is commonly known as a sand oil surface, that is, it is coated with a liquid containing oil or varnish. Then the body is placed in an oven to dry and then receives another surface of the same liquid, but the first applied coat is sand papered prior to the second coat being applied, and then the body is returned to the oven to again be dried. This operation may be continued until the body has a desired surface and such operations are slow and tedious because considerable time is required in an oven for drying, and the surfacing liquid retards sanding off; the surface due to the oil and varnish in the surfacing liquid. Besides, from a commercial standpoint considerable labor is involved and the maintenance of an oven expensive.

This composition, when used as a surfacer, dries in approximately a half hour without the aid of heat; contains no oil or varnish, saves sand -paper and time incident to finishing off the. first coated surface to receive the second coat, and materially increases production in any factory Where vehicle bodies orother articles of manufacture are provided with highly finished'surfaces.

From the foregoing it will be noted that this composition may be considered as a sand surfacer and considerable importance is attached tothe gum thus as an essential element, which obviates the necessity of using any oil or varnish.

What I claim is 2-- 1. A filler composition consisting of graphite, two pounds; fullers earth, eight pounds; gum thus, one pound; and sufii- H cient turpentine to cut the gum thus and make one gallon of the composition. 7 2. A filler composition comprising gum turpentine. as a solvent for the gum,-

fullers earth as abody, graphite as a smooth to serve as a binder for the graphite and surface material, and in which composition earth.
